Submission + - Why winners become cheaters (

JoeyRox writes: A new study from the Hebrew University of Jerusalem reveals a paradoxical aspect of human behavior — people who win in competitive situations are more likely to cheat in the future. In one experiment, 86 students were split up into pairs and competed in a game where cheating was impossible. The students were then rearranged into new pairs to play a second game where cheating was possible. The result? Students who won the first game were much more likely to cheat at the second game. Additional experiments indicated that cheating was also more likely if students simply recalled a memory of winning in the past. The experiments further demonstrated that subsequent cheating was more likely in situations where the outcome of previous competitions was determined by merit rather than luck.

Comment Re:Yet 'optionals' somehow made it through (Score 1) 339

The only thing this optional construction adds is a redundant data member (used to track whether the optional is assigned or not), whereas a traditional null/nil check can use the original field value to make this determination.

Regarding the multiple redundant checks that optionals encourage, those mostly come from optionals chaining.
